I would not be suspect of this gun as a whole at all, but then again I'm not spending 6500 for it.
The thing I see that is most unique is a C grade with single animal motifs. "Most" have double dogs and double ducks on guard.

Clearly two screws are incorrect and possibly the buttplate has replaced a cut stock and old recoil pad but nothing else looks out of whack to me.

I have good photos of the following comparisons should anyone want to see them.
35000 CE. Much less ornate than subject. Same barrel markings same quality damascus.
38000 CE. Much more ornate than subject "Lefever Arms Co Krupp Fluid Steel" fine print on both barrels
39000 CE. Lateral move on ornamentation. Less on sideplates, more on bottom. Same barrels and marking as subject gun.
